Natal probably isn't blindly guessing as implied, but is extrapolating based on a reasonable number of parameters including skeletal position, motion and velocity information, inverse kinematics, biophysics, etc.
Hide the move controller behind your back and shake it for a bit and it will get lost, because you can only deduce so much info from accelerometers and there are too many unknown variables. I'd wager that for body position Natal does a better job of figuring out joint/skeletal position than Eye/Move because of the 3d data, but it is expected to.
